Anyways I think the problem with relay triggering might have something to do with lpt port, once I connect lpt cable relay just triggers on it's own, I found an old bob and plugged in does same thing with relay, changed lpt cables same thing,
Identify which LPT pin energises the relay than change it's Active Low state in Config. / Ports & Pins / Output Signals - does the relay still energise ?.
